Casual contacts of Sydney's new COVID-19 cluster have been asked to cancel weekend plans as tracers race to stem the outbreak amid fears it's being passed from fleeting contact with infected people.

As the number of cases grew on Friday to three people, so to has the list of exposure sites increased.

The highly transmissible Delta variant has caused the exposure sites to spread from the Eastern Suburbs into other parts of Sydney, with new positive cases having shared little more than a fleeting crossover at the same store or cafe as Patient Zero, a limousine driver.

Caught on CCTV in the Myer at Westfield Bondi Junction was the fleeting crossover last Saturday between Patient Zero and a new case, a man in his 50s.

"At the moment they know that they've placed him on the same floor in the same section of Myer," Chief Health Officer Dr Kerry Chant said.

The "fleeting interaction" was enough to spread the virus.

The following day, Sunday, a woman in her 70s was infected at the Belle cafe in Vaucluse — she was sitting outside while Patient Zero was inside.

"The randomness of that is what makes it scary," NSW Premier Gladys Berejiklian said.

The list of exposure sites stretches from Bondi Junction and Vaucluse across to North Sydney, Campbelltown, Newtown, North Ryde, Redfern and Zetland.

Masks have become mandatory on public transport again for the next five days and the premier has asked anyone who fits the criteria of a casual contact to cancel their weekend plans to avoid the possibility of a further spread of the virus.

NSW Health on Friday night issued a new alert adding more venues to the list of exposure sites at Westfield Bondi Junction. (Full list in our graphic below.)

The infected limousine driver also visited David Jones on Level One on Saturday from 10.55am-11.15am before heading to Myer on Levels Two and Four from 11.15am-11.50am the same day.

As a result, anyone inside either of the department stores at Bondi Junction are now considered close contacts, who must contact NSW Health, get a COVID-19 test as soon as possible, and quarantine until 14 days have passed since they were at the venue, regardless of the result.

You will be considered a casual contact if you visited the Bondi Junction Westfield food court between 1.15pm-1.45pm on Sunday, June 13.

Anyone at all who was at the shopping centre on Saturday, June 12 between 11am-12pm and Sunday, June 13 between 1pm-2pm and 4pm-4.30pm, are being asked to get tested even if they were only in the carpark and have no symptoms.

Anyone who visited the Tea Gardens Hotel Bondi Junction's gaming room on Sunday between 5pm-5.15pm is considered a close contact and must immediately get tested and self-isolate for 14 days regardless of the result.

Anyone who visited the shopping centre at any time between June 11 and 18 has been told to monitor closely for symptoms and get tested if they become unwell.

The nursery Eden Gardens in Macquarie Park was also listed as a casual contact, with people who visited between 12.30pm-1pm on Sunday asked to get tested and self isolate until a negative test is received.

A Greek helicopter pilot was charged Friday with the murder of his British-Greek wife, whose death he had initially claimed was caused by burglars during a brutal invasion of their home on the outskirts of Athens.

Pilot and flight instructor Babis Anagnostopoulos, 33, was arraigned for the May 11 killing of Caroline Crouch, 20, who died of suffocation.

He was led in handcuffs and a bulletproof vest to an Athens court and is due to return next week to give evidence.

In brief remarks to reporters, his lawyer confirmed that he had confessed to the crime, adding that he had expressed remorse for his actions.

Police investigators said analysis of data from a smartwatch worn by the victim had helped reveal inconsistencies in the pilot's account of events.

The pilot had publicly claimed that armed robbers broke into the couple's home and tied up and gagged him and his wife in their bedroom as their months-old daughter slept. He had said the men stole cash before escaping.

The account shocked the nation and prompted government officials to announce a €300,000 ($475,000) reward for information about the crime.

Their daughter was unharmed, but the family dog was found choked to death on a leash, hanging from a staircase rail, authorities said.

"Everything was staged for the crime scene to look like the scene of a robbery," Costas Hassiotis, director of the greater Athens homicide division told reporters, adding that the suspect had tied his own hands and those of his dead wife.

He said the examination of mobile devices, a smartwatch with a heart rate monitor used by Crouch, and cameras, had established a timeline that contradicted with the pilot's testimony.

Hassiotis said forensic experts established the time a memory card had been removed from a security camera, adding to the evidence against the pilot.

Anagnostopoulos was detained after authorities summoned him for questioning Thursday while he was attending a memorial service for Crouch on the Aegean Sea island of Alonissos, where she grew up.

He was flown to Athens by helicopter from the nearby island of Skiathos, and interviewed for more than six hours before police announced that he was a suspect.

In a May 16 post on Instagram, Anagnostopoulos uploaded an undated photograph of the couple on a trip to Portugal for a wedding photoshoot, writing: "Always together. Farewell, my love."

A coroner has found Queensland schoolgirl Tiahleigh Palmer likely choked or asphyxiated to death at the hands of her foster father Rick Thorburn, who may also have been sexually abusing her while she was in his care.

In handing down her findings into an inquest into Tiahleigh's death, the coroner today rejected Thorburn's account that he "accidentally suffocated" her as she attempted to leave their Logan home.

The 12-year-old's body was found partially submerged in the Pimpama River, west of the Gold Coast, six days after Thorburn reported her missing in late October 2015.

Her body was badly decomposed and she was wearing only a pair of torn underpants.

A near year-long police investigation revealed Thorburn had murdered Tiahleigh at the family's Chambers Flats home, south of Brisbane, on October 29, 2015.

He then dumped her body after his son Trent confessed to his mother Julene and a cousin that he had sex with Tiahleigh and feared she may be pregnant.

He later pleaded guilty to murder, interfering with a corpse and two counts of perjury and was sentenced to life imprisonment.

On day one of the inquest, Thorburn claimed the schoolgirl stopped breathing while he was "carrying" her up the family's driveway, following an argument about her refusing to go to bed.

He had been home alone with her at the time.

"I do not accept that Richard Thorburn accidentally killed Tiahleigh. I find that he did so deliberately," Deputy State Coroner Jane Bentley found.

The coroner found the lack of injuries to Tiahleigh's body or evidence at the Thorburn home indicated it was "most likely" that Thorbun choked or asphyxiated her.

She found it most probable he killed Tiahleigh because he was worried Trent's abuse would be revealed, however it was also possible he had abused her himself and was worried that too would be revealed.

In 2016, Thorburn was convicted of sexual offences against two girls, aged four and 11, who were in his wife's care at the same time Tiahleigh was living at the home.

"He had access to Tiahleigh – his family all gave evidence that he and Tiahleigh would have been alone together," the coroner found.

Tiahleigh had told her foster mother she "had a secret" in the months before her death and told her that if anybody knew about it, she would be removed from their care.

She noted Thorburn had also refused to explain why Tiahleigh was found wearing only underpants or what had happened to her clothes.

However, she said there was only circumstantial evidence that Thorburn had been sexually offending against Tiahleigh, which meant she must conclude that the most probable reason for the murder was to cover up Trent's abuse.

The coroner found Thorburn was "completely without remorse" and had not cooperated with the inquest and recommended that be taken into consideration when he becomes eligible for parole in 2036.

She made no recommendations relating to the involvement or any failings by government agencies in Tiahleigh's case, noting they had been dealt with in numerous reviews, including a broad whole-of-government review of policies and procedures concerning missing children by the Queensland Family and Child Commissioner which made 29 recommendations.

Thorburn's wife, Julene, served six months in jail for perjury and attempting to pervert the course of justice.

Their son Trent was released on parole after 16 months in prison for incest, perjury and attempting to pervert the course of justice.

Their other son, Joshua, served three months in jail for perjury and attempting to pervert the course of justice.

Storm victims fear they will be tens of thousands of dollars out of pocket despite hardship payments from the government as in some cases insurance only covers a small portion of the massive clean-up bills.

Thousands of Victorians are still without power and over $222,000 worth of personal hardship payments have been issued to almost 200 households since last week's violent storm.

Dean Chapman said he's been crushed to learn insurance only covers 10 per cent of the bill for the damage done to his berry farm in Wandin East, which has been in the family for three generations.

"I wanted to cry really, it was devastating," Mr Chapman told 9News.

"We're probably looking at $50,000 worth of damage there we've got to find out of our own pockets."

A further 120 ADF personnel are expected to start arriving from tomorrow to assist with the mammoth clean-up, as locals continue to count the cost of Mother Nature's fury.

Acting Premier James Merlino today confirmed there were still 5634 households without power, with the majority affected in the Dandenong Ranges.

According to energy provider AusNet, 4629 customers may have their services restored between today and Sunday.

"But as we know, there will be a number of weeks in the depths of winter where many thousands of people will be without power," Mr Merlino said.

"So yesterday, we announced a prolonged power outage payment of $1680 per week extended to all eligible households without power at Thursday, 17 June."

The requested defence members would assist with road clearance, general clean-up, community assurance and doorknocking.

"We have over 1000 people on the ground in affected storm areas right now and in addition to that, around 390 staff from AusNet working hard to get people back connected to power," Mr Merlino said.

There are 119 properties that have been deemed inhabitable and 112 that are damaged, but habitable.

Mr Merlino said the storm damage to properties, including farms, was still being assessed.

"We look at livestock that has been lost, farm properties that have been damaged," he said.

"That assessment is happening right now."

A man has been jailed for more than two years for bashing the boss of a Thredbo ski resort after he was kicked off the slopes for bizarre behaviour while dressed up as a Star Wars character.

Nearly four years ago Keith Wass took to the slopes dressed as Chewbacca and he was a crowd favourite before two parents complained about his bizarre behaviour.

Thredbo CEO Jordan Rodgers told Wass he was being kicked off the slopes, the resort boss was then knocked unconscious with a snowboard, needing surgery to remove part of a tooth from his cheek.

In a victim impact statement, Rodgers said the the attack changed him forever.

"I experience anxiety whenever Star Wars is mentioned … I am forever looking over my shoulder, imagining someone might be coming from behind".

Wass identifies as a "Pastafarian" and the colander he wore on his head to court is a symbol for the satirical Church of the Flying Spaghetti Monster.

It was agreed in court that he suffers from mental health issues, but the judge refused to accept that as an excuse for the attack.

Wass was sentenced to a maximum two years and four months behind bars.

He refused to do community service which effectively ruled him out of a suspended sentence.

He will be eligible for parole in October next year.

Two Sydney divers have had the experience of a lifetime, swimming with a humpback whale off the NSW South Coast.

Trina and Alvin Toh took to the waters off Jervis Bay looking for a glimpse of a migrating whale, but instead were treated to a close encounter with a juvenile humpback.

"This whale kind of just slowly came around and we started screaming," Trina told 9News.

"He did just really playful turns, and spins and spyhops right in between us and kind of just playfully glided around us."

Humpbacks only visit the region for two months a year each winter.

Trina and Alvin's encounter lasted for more than five minutes before the humpback disappeared into the deep.

Detectives have located what they believe to be human remains in their search for missing Melbourne mum Kelly 'Ju' Zhang.

Police began a search for the 33-year-old at the Wollert landfill site on Bridge Inn Road on June 15.

After three days of scouring the location, officers found what they believe to be human remains and a crime scene was established just before 2pm today.

Ms Zhang was last seen at her Winchester Avenue home in Epping about 5.30pm on February 1 before she disappeared.

The coroner has been notified of the discovery and a post mortem will be performed.

Police said the search involved three essential phases using mechanical and physical aspects, including machinery and about 20 police members rummaging through waste.

Police had narrowed the search to a "very specific" area and after today's find, Crime Command Assistant Commissioner Bob Hill said while it was difficult, officers wanted to make sure they got answers for Ms Zhang's family.

"I commend the Missing Persons Squad, Crime Command and other members of Victoria Police for their tireless efforts during this investigation," Assistant Commissioner Hill said today.

"Our members have worked under very difficult and trying conditions to ensure that every avenue of enquiry has been exhausted so we could provide answers to Ju's family and friends.

"We know this has been an incredibly difficult and traumatic time for them. We hope that this will bring the closure they need and Ju can finally be laid to rest."

Ms Zhang's parents arrived in Australia several weeks ago from China with police giving them regular updates on the progress of the investigation.

The expanded search area comes after a number of searches for the woman took place in bushland in the Heidelberg West and Alphington areas earlier this year.

At the time Ms Zhang went missing, she was believed to be wearing a pink nightgown and possibly pink slippers.

Ms Zhang's partner, Joon Seong Tan, 35, has since been charged with her murder.

Mr Tan was arrested on February 10 after police found him at Melbourne Airport.

While charges have been laid, police still encourage anyone with information that may help the investigation to contact CrimeStoppers on 1800 333 000.
